Expert's answer

A tennis ball is fired from a potato cannon with an initial speed of 100m/s at an angle of 37 degrees above horizontal. Write the initial velocity in component form (Vx, Vy)

The horizontal velocity component:

Vx = 100[m/s]*cos(37°) ≈ 79.86 [m/s]

The vertical velocity component:

Vy = 100[m/s]*sin(37°) ≈ 60.18 [m/s]

The initial velocity in component form: (79.86, 60.18).

The horizontal velocity component:

Vx = 100[m/s]*cos(37°) ≈ 79.86 [m/s]

The vertical velocity component:

Vy = 100[m/s]*sin(37°) ≈ 60.18 [m/s]

The initial velocity in component form: (79.86, 60.18).
